After Months of Winter Outages, Ukraine Faces Power Supply Interruptions Amid Gloomy Skies

The hum of generators, which became a familiar backdrop during the winter months, once again echoed across Ukraine as cold and overcast weather triggered new electricity outages in the country. On January 22, 2026, in Kyiv, emergency services established mobile heating points to support the population during power and heating outages.

The arrival of early spring last month brought sunny days that helped stabilize Ukraine's energy system, which had suffered serious blows. Solar energy partially compensated for the deficit left by continuous Russian attacks on the country's energy infrastructure. These strikes destroyed 9 gigawatts of generation capacity, equivalent to the total capacity of Slovakia.

On sunny days, Ukrainian solar power plants generate over 3 gigawatts (GW) of energy. However, the return of gloomy weather and rain in recent days has limited the sun's ability to provide electricity to Ukrainian households.

Power outages have been reintroduced in some regions of the country since the onset of bad weather, including in Kyiv and several western oblasts. Frontline regions are facing difficulties regardless of the weather, as Russia continues to target their energy infrastructure.

"This is a matter of weather conditions. If the temperature rises and solar activity increases, we will be in a good position to cover all our needs," noted Vitaliy Zaichenko, the CEO of Ukrenergo, the state operator of Ukraine's power grid, in an interview with the Kyiv Independent on April 8.

The situation in the energy sector is complicated by a number of issues, including damaged facilities, routine power plant shutdowns, and rising production costs.

While Ukraine has managed to restore 4 GW of generation capacity since the beginning of winter, many thermal and hydroelectric plants are currently undergoing repairs following Russian attacks.

Combined heat and power plants, which simultaneously generate heat and electricity, were shut down at the end of the heating season in March. While this is standard practice, there are currently few alternatives to replace them.

Additionally, energy companies that generate electricity from natural gas have reduced production after Kyiv completed a special gas price agreement, which increased their costs.

Ukraine's three nuclear power plants, which provide more than half of the country's electricity, are also undergoing annual maintenance, and blocks are periodically shut down during spring and summer. Typically, this does not impact Ukrainians too severely, but with limited alternative sources this spring, it has become a heavier blow for the population.

Initially, Ukraine compensated for the deficit by importing more electricity from Europe in early March when maintenance of nuclear facilities began. Since then, electricity prices in Ukraine have fallen from extreme winter highs and have even become lower than in some EU countries.

Consequently, electricity imports have decreased. This is partly explained by Ukrainian traders' reluctance to buy electricity at higher prices abroad only to sell it cheaper in Ukraine, Zaichenko noted.

However, this also indicates that the energy crisis in Ukraine, which left millions without heating and electricity as temperatures dropped to -25 degrees Celsius, is stabilizing. The current outages, although irritating, last only a few hours, unlike the multi-day periods of darkness experienced during winter.
